2) History

This small company is only interesting because it developed within a very short time from a low grade-watch assembler to a manufacturer of quality movements - however without longer success due to the contemporary development of the quartz watch.
The automatic calibre of this company became in 1974 the base of the smallest automatic chronograph of that time. It was designed by Dubois-Depraz, and produced by Kelek.
